Application filed october a, 1912. Asefj'iai15m-resem.

Be it known that I, Heeey nieuwe, a-'citizenof the-United States, residing'- at Taunton, in the .county O f Bristol, 1n the State of Massachusetts, have-'invented an Improvement in Shock- Alosorbers, of which the following is a specification.`

This 'nve'ntion' relates to' shock-absorbers for automobiles-sand the like vadapted for connectionjbetvveen the frame and the axle resist movements of the-frame and' axle,

t bothd toward and from each other.

The invention lhas for its object the provision of one or more springs or cushions 'y and improved means' for supporting them A' and for compressing' each spring upon relative movements of the frame and axle both 'toward and from each. other.-

Figure 1 is a-plan vievv of a .shook-abf sorberfembodyingthis invention, Fig. 2 is a side elevation and partial vertical section of the shock-absorber shown in Fig. 1. Fig.

3 is a transverse vertical setion of the shock-absorber shown in Fig. '1, taken on` the dotted line3-3. Fig. l is a side elevation and' partial vertical section of a modified form of shock-absorber. and 6 are plan views of means for adjnsting the spring.

10 and 12 represent', respectively, two di. verging armshavinpj. holesv at their outerv ends to receive bolts ll and 13 for conneet ing said arms, respectively, with the frame end axle v or other parts of the running' gear-l o an automobile or other vehicle. The`inner' ends of said arms `have curved faces 14, l5, for engagement with each other,

which 'permit a' rocking. movement of the: arms as the', frame and axle approach and recede from each other. The 'curve engagging-faces may be arcs of circles ormay be cams.- Said arms are held against lo ni directions,

gitudingrl and transverse movement 'with respectvto eachother yetA are permitted to; rock, and said rocking movement, in both iS resisted by arm 10 has a recess 16 1n its upper side,

above or opposite its curved engaging-face' 14, which receives ,a spring 18, 'consisting o f a block of rubber, but in lieu thereof any suitable form -ofspringmay be employed A plate 20- is'iheld against the onter'end of said spring, 'atV the entrance to therecess, by

a nut 22. arranged Ion the'screW-threaded.`

`tends 't l I fandthrou'gl a' centerehole inv the spring 18, and three .h

springs. As shown in Figs. l to 8, the inner end of the shank-pio rough a center-hole in the plate 20,

allele 1n the. arm, and thehead 26, of said olt 1s arranged in a recess formed in the engaging-tactile." Said'head 2 isv nien 24,- Qf a bon, which naar ex Patented-Sept. 16,1913. i

made. as an ear for pivotal-connection with other ears'and extends-fbeyondthe engagins-face, and? as' hereffshown, has. .light-. i

anguladyjformed shoulders.v The inner end of tl1 e-farj'1 2 has q .recess 17 in1i ts. vunderside below or opposite its curved -en- :face l5, which receives' af Serinslf Censis ing of ablok of rubber,- or, inf' `lieu thereof any soitable forml of fspringrna-y be .employedj A plate 21 is helda'izainst the seein o'ilteiend 'of said Spring, atv-the entrance-invk to the recess," by a nt'23' v'ar-mugred on the screw-threaded shank-portion'. 25ct aY bolt,

which latter extends throueha center-1101 in the plate l, and through a center-'hole' in the serine 1.9,

and through a holein the' arm, and the head2? of said bolt is alfyranged in a recess formed in the engapgi-ngw face 1 5 lSaid head 27- is composedI of a pair of .ears which extend beyond vthe 'engalglng-faee, and which receive' between t em the ear 26, for vpivotal connection therewith, and,as here shown, said head or the basefof the ears composing it have right-angiilarly formed shoulders.

30 represents a ipivotin which extends A' transverse and 27.A aidpivotpin is` arranged at the normal point of' contact oft-he two engagingfaces intersecting' said feint, and .hence maint furthermore, said pivot-,pin has enlarged end portions or'heads. see Fig. 3, which extend over the outer sides of Ybo tharrns,. at

the sides of the e ngaging-faces. Bj'means of these pivotally connected-bolts't e arms are yconnected together and held against longitudinal and transverse movement with respeci 't0 each other, yet permitted t0. rock,

through. h es in the earsQG andby means yof the springs said rocking movement is resisted in both direct-ions, for

it will b e observed that-'as tbeyarms ap,- pioah each other and rock on Atheirengaging-faces in one direotion botlisprings will er and yrock on their engagingfaces upon both movements of due to the fact that'yeach spring .is connected be 'co rrigressed1 'and as the arms recede from `eachv ot `in the other direction both 'springs will be Compressed liiecampression Qt'thesprings lit with the harm. other than l'iears it.

The recesses 1G and' 17 aie made a littleA larger.in' diameter than the springs 'or cushions IS-and 19, vand When said springs or cushions arecompressed and thereby caused 'to expand laterally4 thesivalls ofthe recesses serve to limit such expansion, so

that they are supported by, said Walls against undue distortion, "yet even When in engagement Witlisaid Walls they may be still further compressed toa slight extent.

'Referring iolfige, the arm 10 is made` like the armi() of Fig. 2, and has a springv 1 8 above its curved engaging-face, and a bolt 24 extends` through said spring having as its head an 4ear 26 which occupies a position between tivo ears arranged directly on the 'inner end portion of the arm 50,y and said arm 50 has a straight engagingface 55 upon which theinner endportion .of the armv rocks. y'In this. instance, but one spring 'is employed, and this spring is lcompressed i upon both rocking movements of the arms owing 'to the fact' that it is borne' by one arfmabove and intermediate thdength of its engaging-face and is connected Withthe oth'erarrn. :Reerringto Figs5 and 61,'60'repre'sents' circular plate designed .tobe placed on top of the spring18, and havin projections on its upperv side with incline faces,l and '65 represents a circular plate'designed to be' placed on top of'. the pla-te GOhaVingproe jections 66 on its under side-With inclined faces -for cooperation with the projections 61 and`said plate 65 has a hand-piece 67 by which itfmay be turned. lThe bolt 24 e'X- tends through centerholes in' said plates G0 and 65, By turning the plate 65 the projections thereon ride up onA the projections the 'tension of the spring 18.
